IMPROVED SELF-ROCKING CRADLE.

Specification forming part ot' Letters Patent No. 511,815, dated May 15, 1866.

To all 'whom fit may concern:

Be it known that I, BENJAMIN BRAZELLE, of Nashville, in the county of Washington and State of Illinois, have invented a new and useful Improvement in SeltRocking Cradles, 85e.; and I do hereby declare that the following is a full, clear, and exact description there of, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure lis a vertical cross-section of a cradle with myimprovement attached, taken through the line .fr x, Fig. 3. Fig. 2 is an end view of the same, the cap or side of the case that contains the clock-work being removed. Fig. 3 is a horizontal section ofa portion ofthe same, taken through the line y y, Fig. 1.

Similar letters ot' reference indicate like parts.

My invention has for its object to furnish an attachment for cradles, cribs, Ste., which shall be self-rocking and adjustable, so that the motion may be long or short, and slow or fast, as may be desired; and it consists of the rockcr-wheel, the slidin g verge, the lever, the stud, and the hinged foot, in combination with each other, with the clock-work, and with the frame of the cradle or crib, as hereinafter more fully described.

A is the frame, and B the rockers, of the cradle, about which there is nothing new.

C is a case attached securelyto the frame of the cradle, and within which is placed the clock-work that gives motion tothe cradle.

D is the secured to the side of the case and the other end to the axle of the cog-wheel E. rlhe cogwheel E is made to revolve with its axle by the pawl F and ratchet-wheel Gr, said pawl being held down in its place by the spring H. The cogwheel E meshes into pinions ou the and imparts motion to said wheel, which in turn meshesinto pinions on the axle J and communicates motion to said axle. The axleJ projects through the inner side of the case C, and to its end is attached the rocker-wheel K. The outer face of this wheel is provided with projectingteeth or pins, upon each of which is placed a small friction roller. These teeth or pins are arranged in mainspring, one end of which is two circles, the out-er circles being near the circumference of the wheel and the inner about half-way between the outer circle andthe center otl the wheel, as shown in Fig. 3.

To the frame of the cradle, orto the side of the case C, is pivoted one end of the lever L.

The other end is connected to the foot M by a hinge-joint, as shown in Figs. l and 3. This joint has enough play to allow the lever to make its movements in rocking the cradle, but not enough to allow the foot M ever to get out of its proper relative position.

N is a sliding verge attached to the upper side of the lever L, to which it is secured by a screw passing through a slot, nf, in said sliding verge N. The lower end of the verge N is cut away, as shown, leaving a projecting part, u2, which comes in contact" with either theouter or inner row of teeth on the wheel K, according as the said verge is drawn up or pushed down. To the edge -of the sliding verge N is attached a stud, O, having a slot made in its upper end, in the form shown in Fig. 3.

To the frame of the cradle, or to the side of the case C, is pivoted one end of a detent or lock-lever, P, the other end of which is made in the form representedin Fig. l. To the side of the lever l is attached a pin which enters the slot in the stud O, as shown in Figs. l and 3.

R isa set-screw passing down through a nut in the upper side of the case C, and its lower end rests upon a spring, S. One end of this spring is attached to the upper side of the case O, and its other end carries a friction-roller, which, when the spring S is forced down by the screw R, comes in contact with theaxle of the wheel I and retards the motion of the wheels.

In using the cradle, when it is in the position represented in Fig. l the force of the spring D presses the pin l down upon the part azot the verge N. lThis raises theleft-hand side of the cradle, giving it an impulse toward the right. This allows pin l to slipfrom the end of the verge N and brings pin Sagainst the tooth of the lever P. 0n the return swing, or movement of the cradle toward the left, the

stud O raises the leverP away from pin 3 and l allows pin 2 to come into contact with the end v The rocker-Wheel K, the sliding' verge N, the lever L, the detent or lock-leverl?, the stud O, and the hin ged foot M, in combination with each other, with the clock-work, and with the frame of the cradle or crib, substantially as herein described, and for the purpose set forth.

BENJAMIN BRAZELLE.
